Trench MOSFET


Trench MOSFET technology is the newly introduced MOSFET technology in which the gate electrode of the MOSFET is buried in trench etched in Silicon to get a vertical structure to enhance the channel density. The MOSFET using the trench gate is called TrenchMOS or UMOS (since the trench is U shaped).The main feature of TrenchMOS is that it lacks the JFET effect.

Power MOSFET


MOSFET is the Metal Oxide Semiconductor Field Effect Transistor used for switching applications or to amplify signals. In the MOSFET, a voltage applied to its oxide- insulated gate to induces a conducting channel between the Source and Drain electrodes. This causes the flow of current. The channel may be n-type or p-type and based on this, MOSFETs may be n-MOSFET or p-MOSFET. Previously, metal was used in the gate but now polysilicon is used in the gate but the efficiency is more in metal made gate channel.
